Magnet Specs

  • 2-mm thickness

  • Outer diameter = 9.7 mm

  • Inner diameter = 1.5 mm

  • 6 poles (3 north and 3 south)

Encoder Hall latch

TMAG5110 (2 independent outputs) or TMAG5111 (speed and direction) 2D latch

Motor

  • Gear Ratio = 120:1

  • 1.5-mm diameter motor shaft

  • No-load speed at 4.5 V: 150 rpm

Maximum transitions per Hall latch output

120 gear ratio × 6 poles = 720 transitions per wheel revolution
